5.7L

Yesterday, over on LS1Tech.com, “Fastdriver1992” posted up some pictures of his engine… err… what was left of it at least. When it was in one piece, it was a beautiful, all aluminum LS6. Today it is a pile of aluminum which once resembled a 5.7L Corvette / Cadillac CTS-V engine. These engines are light, make gobs of horsepower, are fuel injected, and are nice to look at. Did I mention they make gobs of power? Oh yes, I believe I did…

Fastdriver1992’s LS6 is typically being used to rocket his 1975 Corvette down the 1320 at 119mph in 11 seconds flat. It was making roughly 450 horsepower at the top end of the track, around 6000 rpm when all hell broke loose. After some detective work, the theory is that his engine broke a valve, which danced around the combustion chamber, bent the connecting rod, ate the piston, and exploded the block. 5 seconds later, ouch.
